Distally based abductor digiti minimi muscle flap.

The abductor digiti minimi muscle flap is known as good tissue coverage for the lateral ankle and heel. For reconstruction of the distal portion of the foot, the distally based flap of this muscle can be useful, effectively utilizing the blood supply through the plantar arch communication. A case of frostbite of the right fifth toe is reported, which we successfully repaired with a distally based abductor digiti minimi muscle flap. In addition, some information on distally based use of the muscles of the foot is presented.
